A bit of an anti-recommendation here... we've had nothing but problems with the Sierra Wireless 320U units supplied by Telstra - they randomly drop out needing a hard reset to correct and SMS doesn't work reliably (see my post from mid last year - since followed up with Mikrotik who were unable to solve the issue). We've also never been able to get Direct IP / LTE working on them. -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Alen Orsolic Sent: Friday, 27 February 2015 4:06 PM To: 'MikroTik Australia Public List' Subject: [MT-AU Public] LTE/4G USB Modem Hi All, Due to a number of recent enquiries I am seeking feedback as to known working 4G USB modems, in particular Telstra network supported devices. As we don't stock or use any ourselves any comments and or suggestions would be greatly appreciated. I have canvassed the MikroTik hardware support Wiki, but would appreciate any positive working and in production solution. A number of customers are looking at implementing a failover based product but, current 4G USB modems purchased from Telstra have yielded unsatisfactory results.
